Probably not much help here, but I live in Palm Bay, FL and have been getting dozens of ghost shrimp from Petsupermarket. $1.39 a dozen. I use them as feeders for my F8 puffer. I was also told of a mom and pop store, West Melbourne Aquarium that has ghost shrimp about a buck a dozen. Never bought shrimp there, but I did buy a fancy goldfish from him and was very satisfied. Seems relatively knowledgable as well.
